• Connect the pressure hose to the equipment to be tested with valve V1 opened and valve V2 closed.
• Open one or several purge points in the installation. Remove the handle-locking hook and pump liquid until all air has been purged from the system. Close the vent points and then fill the installation operating the pump handle with ample movements.
• Keep on pumping until the test pressure has been reached.
• Close valve V1.
• If the test pressure is exceeded during the pumping operation, slightly open valve V2 until the required pressure is attained. The close all Vavles.
• If no leaks are present , no pressure drop should be detected in guage readings. At test completion, open both valves V1 & V2.
